Abstract
This invention relates to a non-oxidative method of sweetening a sour hydrocarbon fraction. The method comprises treating a sour hydrocarbon fraction containing mercaptans with an acid-type catalyst in the presence of an unsaturated hydrocarbon at reaction conditions thereby converting said mercaptans to thioethers. Acid type catalysts which may be used include polymeric sulfonic acid resins, intercalate compounds, sollid acid catalysts and acidic inorganic oxide catalysts.
